Title: Three primary colors luminance measuring instrument for color picture tube
Inventor: TEZUKA TOSHIYUKI
IPC: H04N17/04
Filed: 1987-04-16
Abstract: PURPOSE:To attain correction without troublesome adjustment by using a numerical arithmetic operation after binarizing processing so as to apply RGB correction. CONSTITUTION:The light on the screen of a color picture tube 7 is subject to transmission by a filter 8 for a desired wavelength only and the result is led to photodetection sections 9, 10. The output waveform from the photodetection sections 9, 10 has an extreme value every time a scanning line of the color picture tube 7 passes the front face of the photodetector sections. The extreme value is held by a peak detection circuit 11 and led to a binarizing processing section 14 via a multiplexer 13. The quantity representing the luminance being subject to binarizing processing reaches an arithmetic circuit, where the correction is applied through the arithmetic operation.

IPC: B65H54/82
Filed: 1984-05-10
Abstract: PURPOSE:To smoothly wind up a wire onto a dancing wheel without the wire being damaged, in a winding device of a block rotating and inversion type, by using a double deck type block, and by dropping the wire onto the dancing wheel on a turntable after the wire being straightened out. CONSTITUTION:After a wire is wound up by several turns onto a double-deck type block 1 through a guide pulley 8, the wire is introduced to a correcting roll 3 to be straightened. Further, the wire is again wound by a several turns on the above-mentioned block 1, and is secured to the latter with the use of a retaining roll 7. In this stage, the terminal end of the wire is dropped from the retaining roll 7 section positioned substantially symmetrical with a position where the wire enters from the correcting roll 3 to the block 1, onto a dancing wheel on rotation which is secured to the turntable section 4 and is surrounded by a cover 9, and the wire is therefore wound up the dancing wheel. Further, the turntable is separately driven and controlled, so that it may be rotated at an arbitrary speed irrespective of the block 1.

IPC: F23D14/74
Filed: 1985-05-01
Abstract: PURPOSE:To prevent an occurrence of spatial flickering of a front edge of a flame generated by a gas injection flow from sub-holes to an impeller and to reduce a variation of draft in a furnace by a method wherein a flame-holding unit is arranged at a sub-hole gas flow part for supplying gas onto the impeller. CONSTITUTION:Eight gas injection portions 3 are arranged at a throat part 6 and a impeller 7 is installed at the central part. A throat part 6 is formed between a circumference of the impeller 7 and a gas injection part 3, combustion air is injected while being circulated and when a front edge of the flame is formed between them, spatial flickering of the flame is generated. A flame- holding unit 10 is arranged between the flame holding part 8 and the outer circumference of the impeller 7, thereby an occurrence of the spatial flickering phenomenon of the flame is prevented. That is, since the gas flow to be supplied toward the impeller through a gas nozzle 9 is completely kept on the flame- holding unit 10, the flickering of the flame can be prevented.
